| Abstract: | The contents of trace elements in Zanthoxylum nitidum, such as Fe, Cu, Zn, Mg, Ca, Pb and Sn were detected by the flame atomic absorption spectrometry and graphite furnace atomic absorption spectroscopy. The results showed that these methods were simply, precise, sensitive and credible. The recovery rates were in the range from 98.26% to 100.57%. In a conclusion, there are rich of Ca, Fe and Zn in Zanthoxylum nitidum. |
